I agree with what the recommendation says, but don't see the point of having it in the document.
1) it doesn't even mention AQM, 2) the behavior of TCP and SCTP is defined in other RFCs, what's the point of saying "they should actually do this and that"? To guide people diverging from the standards, or prepare future standards? For the first, I'm not sure if we should care much in an RFC about people that don't care about RFCs; for the second, I think we have lots of guidance notes in this direction already (some would be in RFC5783, e.g. RFC2914)

Cheers,
Michael

This is the question of TCP/SCTP Congestion Control: I would like to, as a community, recommend that it maximize throughput while minimizing delay, which is to say, do so without being overly aggressive.
